The Promise of Solid Lubricants for a Sustainable Future

Advanced Materials, EarlyView.
Lubricants are vital for technology, saving energy and resources. The industry seeks sustainable solutions beyond fossil fuels. Solid lubricants offer extremely low friction and reduce environmental impact, especially in harsh conditions. Can these solids truly replace liquid lubricants, or are they limited to extreme applications?

Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

Advanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

Mechanistic phylodynamic models do not provide conclusive evidence that non-avian dinosaurs were in decline before their final extinction

Cambridge Prisms: Extinction
Phylodynamic models can be used to estimate diversification trajectories from time-calibrated phylogenies. Here we apply two such models to phylogenies of non-avian dinosaurs, a clade whose evolutionary history has been widely debated.

Obituary: Jacob Brodzinsky (January 17,1918 - February 25, 2003) [PDF]

, 2002
Earlier this year, at the age of 85, Major Jacob Brodzinsky passed away at his home in Santo Domingo. It is with great sadness that I write this obituary, because Jake was a great personal friend and professional colleague for over 30 years.

Shapeshifting Nanocatalyst for CO2 Conversion

Advanced Materials, EarlyView.
A multi‐modal in situ characterization of Ag‐Cu nanoparticles during CO2 photoreduction sheds light on dynamic transformations occurring during reaction. The Cu(core)‐Ag(shell) nanoparticles present the Ag replacement by Cu atoms. Ag is trapped at the subsurface forming a Ag‐Cu‐O phase, and the nanoparticle spreads over the substrate.

Role of Liquid Composition in the Transient Liquid Assisted Growth of Superconducting YBa2Cu3O7‐δ Films

Advanced Materials, EarlyView.
The Y supersaturation in the [Ba‐Cu(I/II)‐O] transient liquid composition is the driving force toward YBCO nucleation and growth in TLAG. Tuning the initial (Ba:Cu) molar ratio in the ink composition determines the YBCO epitaxial nucleation through supersaturation control.
